EOCENE MAUL DISTRICT. 



As already indicated, the extent and boundaries of this interest- 

 ing portion of eastern Virginia are as yet in a great degree matters 

 of conjecture. The discovery of an Eocene deposite in the state first 

 announced by me about eighteen months ago, in a communication 

 to the Farmer's Register, lias been followed up by a minute per- 

 sonal examination of some parts of the district in which it occurs, 

 more especially on the James river and Pamunkey. Its existence 

 on the Rappahannock and Potomac has also been ascertained, and 

 specimens have been obtained from a number of intermediate points. 

 With regard to the region South of the James river, though facts 

 have been procured which show conclusively that the deposite con- 

 tinues to the southern boundaries of the state, time has not ad- 

 mitted of such an investigation as would be necessary in defining 

 its extent. A regularly continuing line of observations on the
